Product Description

The Worcester-Bosch Greenstar 24i System is one of a range of highly energy efficient A rated by SEDBUK 2009(Seasonal Efficiency of Domestic Boilers in the United Kingdom) gas-fired condensing boilers available from Worcester-Bosch.

Being a system boiler the Worcester-Bosch Greenstar 24i System requires a hot water storage cylinder but no feed and expansion cistern making it quick and easy to install as well as being efficient and economical to run.

In fact the Worcester-Bosch Greenstar 24i System recycles the heat from exhaust gases that would otherwise be lost through the flue and modulates its output independently for domestic hot water and central heating making it up to 30% cheaper to run than some older boilers.

The storage capacity of your hot water cylinder is the determining factor in the amount of hot water readily available to your household but the Worcester-Bosch Greenstar 24i System with a maximum output of 24kW (kilowatts) or 82000Btu (British thermal units) per hour is typically suitable for a medium or large family house with a traditional heating system.

This boiler is recommended by the Energy Saving Trust.

3/5

They need to simplify the boiler with more thought towards the fitter and the installation process. Access to screws and internal fittings was difficult especially when removing the condense trap. I installed one recently and hoped that they might of addressed those issues, but hey presto, they haven't!

Tradesperson Review
5/5

I have recently had this boiler installed alongside a Joule unvented cylinder controlled by a Nest thermostat. It's a quiet efficient boiler that's providing more than enough hot water and heating for a family of 5 in a 5 bed detached house. Our previous Potterton boiler struggled to heat the house so good choice to change to the 24i.

Customer review
2/5

Whilst the Greenstar 24i uses less gas, I am not able to raise the temperature in our house beyond 21c and that temperature is only achieved by having all radiators at maximum setting, all doors closed in lounge and the heating system on all day...even then it only achieves 21c in the evening.
I live in a semi detacced, bungalow where all external walls have had cavity insulation and where all windows are double glazed. The irony is that I was warmer before the new boiler was fitted 2 years ago.
